The Fronius Energy Management Relay for intelligent energy management

Intelligent energy management is becoming increasingly important. Since January 2009, the private consumption of self-generated PV electricity has been boosted by the German Renewable Energies Act (EEG). The Energy Management Relay is a solution developed by Fronius to optimise the private consumption of self-generated solar power.

Consumers are free to decide whether to feed the generated PV electricity into the grid or to supply power to their electrical equipment. All that needs to be done is to configure the inverter accordingly.

The energy management function in detail
The production meter records the energy yield of the PV system. If the Energy Management Relay on the inverter is deactivated, the generated solar power is fed into the grid. If the inverter produces more than the defined power level, the relay switches and the generated power is supplied to the specified electrical consumers. Power that is not required continues to be fed into the grid. The level of private consumption is derived from the difference between the production meter and the electricity meter.

The energy management function is expected to be available for Fronius IG Plus and Fronius CL inverters from mid-February 2012. Customers will need a Fronius Signal Card in order to take advantage of this feature. The card is included as standard in Fronius CL inverters and can be retrofitted very easily in Fronius IG Plus inverters.
